Title: Rounding process circuit
Inventor: TAKAHASHI TOSHIYA
IPC: G06F7/508
Filed: 1984-07-12
Abstract: PURPOSE:To perform a rounding process at a high speed by using a deciding circuit that decides whether the rounding process means the rise of unit or omission and a circuit that supplies the overflow of upper digits given from a mantissa incrementer and the deciding signal given from said deciding circuit and produces a selection signal. CONSTITUTION:At the outset both the mantissa data and the exponent data obtained before a rounding process are latched by incrementers 104 and 109. Then an increment process is carried out, and only an R2 signal 113 is made active in case the rounding process means the rise of unit and also the carry information given from the incrementer 104 is equal to ''1''. The data on a constant register 105 is turned into the mantissa data at the next timing to select the rounding data with which the arithmetic result of the incrementer 109 is defined as the exponent data. Finally the rounding data is selected and transferred to a prescribed register. Thus just two blocks are needed to complete the storage of the data on a floating decimal point to a prescribed register after a rounding process. This can increase the rounding process speed.

Title: Combustion device
Inventor: WADA CHIYUUZOU
IPC: F23N5/02
Filed: 1982-08-20
Abstract: PURPOSE:To reduce the number of times of carrying out ventilation and re-ignition thereafter and improve the convenience for use by automatically reducing the quantity of combustion to delay the progress of oxygen deficiency before the combustion stops due to oxygen deficiency, in the combustion device with an oxygen deficiency sensor. CONSTITUTION:When the substance of a system of an oxide of tin is used for the oxygen deficiency sensor, the oxygen concentration decreases and the resistance value also decreases. Thus, the input point (e) of an operational amplifier 36 gradually increases. However, since the combustion is continued without carrying out ventilation before that, the room temperature begins to rise up. Therefore, the resistance value of a thermistor 13 becomes gradually small. When the room temperature reaches 27.5 deg.C, the potential at the point (k) exceeds that at the point (g), and the output point (r) of an operational amplifier 43 becomes high, and a transistor 35 is turned ON. Then, the contact falls down on the side 34a, and the combustion becomes weak. Accordingly, with the progress of oxygen deficiency, the room temperature increases, and in accordance therewith, the combustion becomes weak. Therefore, such cases that the progress of oxygen deficiency is delayed, and an electromagnet 4 is actuated and the combustion does not stop, occur very often.

CONSTITUTION:When Si which is of P type and has (100) faces is laminated on (1-102) of a sapphire substrate 1 and islands 3 are selectively made by an etching solution of a volume ratio of nitric acid 50 to hydrofluoric acid 1, then the island side faces are nearly perpendicular to the substrate 1 and (111) does not appear on the side faces. After a SiO2 gate film 4 and poly-Si layer 6 are selectively formed, an impurity of conductivity type opposite from that of the islands 3 is diffused to create layers 31a, 3b thence the layer 6 is made conductive. Next, SiO2 4' is covered by a vacuum CVD method and etching is performed perpendicularly to the substrate by plasma, whereby protection rings 14a, 14b are made. At time time, the rings 14 cover the islands 3, the gate side faces and their vicinity and therefore the outside circumferential walls make contact to the top of the substrate and island at their mildly sloped face, hance wiring disconnection is prevented and leakage current is reduced as well.
